To all whom if may concern Be it known that I, ALEXANDER C. Sci-rU-f- MAN, a citizen'of the United States, residing at Louisville, in the county of Jefferson and ,State of Kentucky,I haveinvented certain new and useful Improvements in Resilient Wheels, of which thefollowingis a speci.-V fication.

This inventionk relates to Awheels for motor vehicles, and more particularly to a wheel y-which is cushioned or resilient, the cushion# ing eii'ec-t being obtained primarily by a pneumatic tire. f l

The invention has for itsr object to pro vide'a wheel of the kind stated in which the pneumatic tire composed of an outer casing and an' inatable inner tube.

The invention also has for its object to provide the wheel with additional cushionying means to obtain greater resiliency, and

also to provide the primary cushioningelement hereinbefore referred kto with aprotecting housing or cover to prevent damage and to preclude the possibility of punctures.

lVith the objects stated in view the vention consists in a novel combination' andv arrangement of parts to be hereinafter idescribed and claimed, and'in order that the same may be better understood, reference ,is had to the accompanying "drawing forming a part of this specification.

Inthe drawing- U Figure 1 isa cross section of the felly. andthe` of the wheel; Fig. 2 is a side elevation of a fragment of said parts; Figs. 3 and 4 are perspective views ofdet'ails and Fig.' 5 is a plan' view vof a further detail. l

Referring sp'eciiically to the drawing, 10 denotes the usual felly of a 4wheel 'and11 denotes the spokes.. .The'hub structure has not been v illustrated as it forms no partof the presentinvention.v The drawing shows a fragment of the felly only," as this suiices for an understanding ofthe invention.'

secured by any suitable means, a pneumatic tire supporting member consisting of a flatl u l and spaced therefroni, and at its ends it 'has inturned -langes 241 lapping the plates; 21` 5 [for a short Vdistance' and secured theretb by f ring 12 seating on the outer surfacenof the f elly and having continuousv outstanding marginal flanges 13 coinciding with the sides ofthe felly and projecting radially. The outer ends of these flanges are formed with inturned resilient tongues 14 overhang ing the ring 12 in spaced relation therewith. The tongues of the respective side :flanges frsr @Erica f ALEXANDER c. SCHUMAN, or Lomsviimn, KENTUCKY.

are spaced from'each otherI at their inner` ends so that' the base portion of an ordinary tire casing 15 may seatvtherebetween, the clencher beads 16 of said casing being gaged by the ends of the tongues. -"l`he cas'- ing V15 contains lthe usual inflatable inner tube 1 7,'and these parts' form the primaryA or main cushioning element 'of the wheeh Eeneath the base of the clencher beads 16 seats a series of spring-supported platesV 18 providing asupport for the base of they casping relation at theirends as shown in Fig. 3; or they may abut at their ends` as shown in Fig. 4, -with said ends-being provided ing. f These plates are arranged 'in ove'i'lapwith abuttingangesll) to 'pie v ent relative- Bet'ween the ring 12 and tliepl'ates 1S being cushioned by Vthe springs and the tongues.

A wheel constructed as hereinbefore described-has a maximum resiliency; the tire casing 15 is not exposed and hence there is no possibility of punctures. vThe fll1er'29 reduces wear ofthe casing to a minimum. If the inner tube 17 should happen to become deflated, the tire cannot get so flat as to become damaged, as the ridges 23 prevent excessive inward displacement,-` and if it is not practicalto make repairs at once, the tire may be continued inv use asit-still has considerable resiliency due to the springv support at the base, and the springsupport of the housing obtained by the engagement of the ridges 23 with the resilient tongues 14.
